Comment 53 for bug 1464917

I wonder if the so called Watchdog Hardware is on my machine at all. I looked for the conf files in /dev/watchdog and found no such directory. According to the website: https://www.freedesktop.org/software/systemd/man/systemd-system.conf.html The manual reads as though its assumed watchdog hardware is there. It states that, "These settings have no effect if a hardware watchdog is not available."

I wonder if anyone assumed the case if it was not there?

It is still my contention the swap management system is at fault here. I have run several tests loading my 3.7 gig ram and 8.1 gig swap then shutting all apps off. Monitoring with system monitor RAM returns to acceptable levels around .9 to 1.4 gig, however the swap never gets below 2 gig even after 30 mins of no load conditions, all apps closed. A swap management system appears to be absent minded.

Turning swap off is the only way I get a clean reboot or shutdown

sudo systemctl reboot or poweroff hang unless swap is cleared first and swapoff fails if data held in swap is larger than available RAM. I am tempted to use SyReq +REISUB just to reboot, why wait for the hang? I check system monitor before running the command below to shutdown to calculate whether the swapoff command will fail then decide how to proceed.

sudo swapoff -a && systemctl poweroff
